Accucel 6 will only give me 3.4amps with plenty of power from the supply.
Why am I only getting 3.4Amps?

Your Turnigy Accucel 6 charger has a maximum rating of 50 Watts. Since watts equals Volts times Amps, that will limit your maximum current output when using more series cells in your LiPo battery. (More cells equals more voltage = higher watts to charge your battery pack, assuming the same selected charge rate in amperes.)

So, you've got 4.2 Volts times 4 cells, that is 16.8 Volts DC. Maximum Amps output would be Amps = Watts/Volts, or Amps = 50/16.8, so maximum Amps will be 2.97 into a four cell LiPo battery.

FYI, I've got two $$$$ Cellpro Powerlab 8 chargers with a 1344 Watt capability. Each is capable of charging my A123 battery packs at 30 Amps, into the A123 battery pack. The battery pack is configured as a 6S4P for charging purposes.

Kyle,
Thanks for the detailed response..it actually all made sense to me!
I am going to get the iCharger 206B 300watt 20 amp charger.
That should work well I think. Should be able to charge upto 2C with 3 4S batteries on the paraboard.
Thanks again.

You're welcome!

Several of my club members have that iCharger, and are quite happy with it.

Let us know how yours works out, for the benefit of the wattflyer readers.

You might also consider the Turnigy Reaktor 300W charger. It's exactly the same charger as the 206b (even uses the same manual) but cheaper.
